we use cec(1).  (not in the standard distribution, but in
/n/sources/contrib/quanstro/cec.tar kernel patch in /n/sources/patch/cpu-cec)
it runs directly on ethernet, not requiring 9p, tcp/udp/il or ip.

one could use consolefs(4) to make this very easy on a large scale;
we currently don't have such a need, so unfortunately i haven't had
time to do this.
